We made this part for our B46 Race Cars after the original part from BMW became NLA. This is also required when swapping a B48 into an E36 or E46 using the GS6-37 or similar transmission. 

This is a very strong 3D Printed aluminum version of the 22316760532 which is no longer available from BMW.  It is the upper trans mount for the GS6-37 and will also work on a GS6-53DZ with a B48 swap into an E36 or E46. We also make a Steel Welded Version

For E46 use in combination with: BMW P/N: 22316760531 OR STROM E46 non-M 6-Speed  Steel Lower Transmission Mount 

For E36 use with: STROM E36 B48 GS6 Transmission Lower Mount
